The WLRG2-LD is a type of snap action, limit switch manufactured by ABB. It is a single pole double throw (SPDT) device that is used to make and break electrical connections to control electrical circuits. The WLRG2-LD is suitable for use in hazardous environments, with an ingress protection rating of IP67.

The WLRG2-LD is a very versatile switch and can be used in a variety of applications. It can be used to control the operation of motors, pumps, fans and other machinery, for on/off control, speed control, reverse control, sequence control and limit control. It can also be used for the control of lighting, security systems and other electrical devices.

The main advantage of the WLRG2-LD is its ability to maintain a high level of performance, even when subjected to a wide range of environmental conditions. It is designed to work reliably in conditions ranging from extreme temperatures (-30°C to 70°C) and in wet or dry atmospheres. It is also designed to resist the ingress of dust and water, and is suitable for use in a variety of industrial and commercial environments.

The working principle of the WLRG2-LD is based on the snapping action of its terminal contacts. When the switch is actuated, two terminals are brought together by a spring-loaded armature, creating an electrical connection. This connection is not broken until the switch is released, and is therefore suitable for use in applications where a secure connection must be maintained.

The WLRG2-LD is also designed to resist the effects of shock and vibration, and is tested to withstand up to 5G acceleration. Thanks to its small size, it can be mounted in confined spaces and even directly onto PCBs. It is available with a range of accessories, such as mounting brackets, height extensions and limit screws.

In conclusion, the WLRG2-LD snap action, limit switch is an extremely versatile device that can be used in a wide range of applications, due to its ability to maintain a secure electrical connection even under extreme conditions. It is also robust enough to withstand shock and vibration, and small enough to fit in confined spaces.
